Charles A. Sennewald, CMC, CPP, CSC is an independent security management consultant.  He has been the Director of Security for Broadway Department Store, Chief of Security for the Claremont Colleges and a deputy sheriff with the Los Angeles County Sheriff’s Department.  Additionally, Charles Sennewald is the founder and first president of the International Association of Professional Security Consultants (IAPSC),  a graduate of the California State University at Los Angeles and the U.S. Army's Military Police School.  Charles Sennewald is the author of six books: Effective Security Management; The Process of Investigation; Security Consulting; Shoplifters vs. Retailers: The Rights of Both; Shoplifting: Managing the Problem; and, The Last Volkswagen.

According to the book description of The Process of Investigation, it “is a book written to address the needs of the private investigator in the security field. Continuing in the tradition of its previous editions, this book covers essential topics which are often overlooked in works that concentrate on the public aspects of investigation. Investigative skills such as surveillance techniques, interviewing and interrogation, evidence, and confessions and written statements are all discussed, and supplemented with updated case studies and examples from the authors own experiences.

Major revisions to The Process of Investigation include mention and coverage of the effects of 9/11 on the security industry, the need to incorporate awareness of terrorism and terrorist activities when investigating any suspicious behavior, and two completely new chapters. Chapter 10 discusses interviewing and interrogations, and is written by Doug Wicklander and Dave Zulawski, premier experts in the field. Chapter 23 addresses the issues of workplace violence, and includes coverage of stalking, domestic violence spillover into workplaces, red flags, and the Theory of Threat Assessment and Management (TAM), among other topics. Additionally, other more minor modifications in legislation that have been passed and implemented since the last edition are addressed throughout the book.”

Michael Khairallah, PSP of Security Design Solutions said of Effective Security Management, it “is an invaluable reference for new security managers and a good tool for the experienced security professional. The book begins with the 30,000 foot view then quickly focuses on each aspect of security management. The reader gets a valuable perspective on corporate culture and the role of each member of the security team, along with good checklist for hiring new employees and creating job descriptions. The book does a good job of explaining on-the-job training and methods for discipline, motivation and promotions.

The book also covers the role of security communications within the company. The book covers techniques for managing the security department by defining methods for risk assessment, planning and budgeting with good examples. The book explains the importance of written policies and procedures and provides techniques for applying computer technology to department management along with ways to employ statistical analysis in managing a security department. There is an excellent section on relationships with Law Enforcement, industry and the community in this book. The most amusing and insightful section was "Jackass Management". The reader is certain to find examples of management types they have experienced in the past and are likely to encounter in the future. The book is well written and well worth the time to read.”

One reader of The Process of Investigation said, “is book is an excellent resource for someone who either has some familiarity in the field of Private Investigations, or for someone who is entering the field and needs to become more familiar with terminology and techniques. The book focuses an entire section on the "Who What When Where Why and How's" for investigations, which I found to be very informative. The information is accurate and is of such high quality that this book is used as recommended reference material for some State Written Examinations for Private Detective Licenses. That should say it all.”

Charles Sennewald, the author, expanded his horizons as an author by penning the Last Volkswagen, a fictional, often comedic tale.  According to the book description, “Competition with foreign products, having adverse effects on American labor, brings about a major political climate, and government. The new pro-labor congress out-laws the importation of foreign goods, including automobiles. Detroit and other industrial centers are reinvigorated and the economy booms. Growing economic success prompts new legislation, which mandates that all foreign-made autos must be exchanged on a government funded trade-in program within a specified three (3) year period. A new powerful regulatory and investigative agency, the Division of Import Controls (DIC) is created to enforce the new law. At the end of the 3 year period possession of a foreign car is a federal crime. In our story the government’s investigative efforts to rid the streets and highways of foreign cars has been achieved.  Except for one: a 1963 Volkswagen "beetle". This story focuses on the chief of the DIC and his dedication and commitment to locate and seize this last unaccounted-for car and a rancher in Nebraska who is equally determined they will never find it. It’s a fascinating journey leading to a clash of two very different kind of "giants", with unexpected results.”

About the Los Angeles County Sheriff’s Department

The Los Angeles Sheriff's Department is the largest sheriff's department in the world. In addition to specialized services, such as the Sheriff's Youth Foundation, International Liaison and Employee Support Services, the Department is divided into ten divisions, each headed by a Division Chief.


 There are three patrol divisions (Field Operations Regions I, II and III), Custody Operations Division, Correctional Services Division, Detective Division, Court Services Division, Technical Services Division, Office of Homeland Security, Administrative Services Division, and Leadership and Training Division.


The Sheriff's Department of Los Angeles County was formed in April, 1850. Elections for the office of Sheriff were held annually until 1882, when the term was increased to two years; in 1894 the term was increased to four years. The first Sheriff of Los Angeles County was George T. Burrill and his staff consisted of two Deputies.


Twenty-four men have served Los Angeles County as Sheriff since 1850: nineteen were elected and six were appointed by the Board of Supervisors to serve the unexpired term of their predecessors. Two were killed in the line of duty. Of those appointed, four were re-elected to the office. The youngest man ever elected to the office of Sheriff was William B. Rowland, who was sworn in when he was 25 years old (in 1871), and was re-elected three times. The record for the longest consecutive service goes to Sheriff Eugene Biscailuz, who completed 51 years in the department, from deputy in 1907, to being appointed Sheriff in 1932 and then retiring in 1958. Our previous Los Angeles County Sheriff, Sherman Block, entered the department as a Deputy Sheriff in 1956 and continued up through the ranks until he was appointed by the Board of Supervisors to succeed Sheriff Pitchess in 1982. In June of 1982, Sheriff Block was elected to a full four year term as Sheriff of Los Angeles County.
